The corresponding electronic dipoles also align in a periodic manner depending on the spatial phase of the incident light. Example for the former include silicon and metallic wave guides used for silicon p ...

... creates an induced electric field Ey which is 90o in phase behind Ein. The total outgoing wave is the sum of Ein + Ey. This wave lags the original wave by a phase = Ey/Ein . This phase delay is equivalent to a wave of amplitude Ein travelling the distance x at a speed v. At speed c the time wo ...

Thomas Young (scientist)
.jpg?width=300)
Thomas Young (13 June 1773 – 10 May 1829) was an English polymath and physician. Young made notable scientific contributions to the fields of vision, light, solid mechanics, energy, physiology, language, musical harmony, and Egyptology. He ""made a number of original and insightful innovations""in the decipherment of Egyptian hieroglyphs (specifically the Rosetta Stone) before Jean-François Champollion eventually expanded on his work. He was mentioned by, among others, William Herschel, Hermann von Helmholtz, James Clerk Maxwell, and Albert Einstein. Young has been described as ""The Last Man Who Knew Everything"".
